sori mga master nakalimutan kung e update ang post ko. signal diode nga lng pala. pero ng pinalitan ko hindi pa rin nag power, when i replaced the opto isolator naging OK na cya. ung opto pala ay iba ung part number (nakalimutan ko) at walang available sa electronic na malapit sa amin,. naala ala ko ung post n master neuclus na PC123 ang ginamit, meron namang available so pinalitan ko naging ok na cya. pogi sayo master neuclus.
